The Pirates just completed a stretch of 13 games in 13 days and will start another slate of 14 contests in 13 days starting Tuesday. Factoring in the workload and the inordinate amount of pitchers on the injury list, it makes sense the Pirates would be adding new relievers to the fray. Over the past two weeks, they’ve supplemented their 40-man roster with three new arms: Montana DuRapau, Geoff Hartlieb and Chris Stratton.
DuRapau has made a good first impression in his first crack at the bigs. Hartlieb raised some eyebrows during his stellar spring training and carried that mojo to AAA and now the majors.
